 Setting Up Your System Hardware

2 - 13

The VSX 3000 and VSX 3000A desktop systems are available with or without 

the built-in Quad BRI network interface. The setup sheet for the IP with ISDN 

system shows how to connect it to a BRI network.
If you purchased the VSX 3000 or VSX 3000A system with IP and ISDN, you 

will need:

• NT-1  device, if the system will be connected to a network that provides a 

U interface

• Up to 4 BRI lines that will not be shared with other equipment
If you connect fewer than four BRI ports on the system’s network interface 

module, connect them in ascending order, starting with port 1.
The diagram below shows a general view of how to connect the VSX 3000 or 

VSX 3000A system to the ISDN using the Quad BRI network interface.
